PHILIP PILON, OF IIINESBURG, VERMONT.

WAGON-BRAKE.

SPECIFICATION forming part of Letters Patent No. 400,942, dated April 9,1889.

Application tiled January 2, 1889. Serial No. 295,250. (No model.)

To all whom t may concern:

Be it known that I, PHILIP PILON, a citi-v zen of the United States,residing at Hinesburg, in the county of Chittenden and State of Vermont,have invented new and useful Improvements in Automatic NVagon-Brakes, ofwhich the following is a specification.

My invention relates to improvements in automatic wagon-brakes; and itconsists in certain novel features hereinafter described and claimed.

In the accompanying drawings, Figure l is a side view of a wagonprovided with my improved brake, showing the brake applied. Fig. 2 is asimilar view showing the brake thrown off the wheels. tive view of therunning-gear. Fig. 4 is a detailed sectional view on the line @om ofFig. 3. Fig. 5 is a plan view of one of the sliding plate-connections,and Fig. 6 shows the plates composing said plate-connection in detail.

Referring to the drawings by letter, A designates the reach, having thebolsters B B secured to its ends, as shown. The axles are arrangedbeneath the holsters and the wheels mounted on the axles in the usualmanner. To the reach, at a point just in advance of the rear wheels, Isecure the transverse bars C C, between the ends of which I pivot thelevers D, to the outer ends of which I secure the brake-shoes E.

The inner ends of the levers D are connected by rods F with the outerends of crossbars G, secured to a supplemental reach, H, as shown. Tothe ends of this supplemental reach H, I secure the secondary holstersI, upon which the wagon-body is secured. To the ends of these secondarybolsters, and on the under sides of the same, I secure the plates J J,which are provided on their under i sides, around their edges,with ribsK, as shown most plainly in Fig. 6. The ribs at the sides of theseplates J are dovetailed to engage the dovetailed ribs L on a plate, M,secured on the upper side of the bolster B, at the ends of the same, andhaving stops N at their rear ends, to limit the rearward movement of theplates J by contacting with the ribs at the ends of the same.

O designates transverse rollers arranged be- Fig. 3 isa perspec-4 tweenthe said plates J and M, to reduce the friction between the adjacentfaces of the same.

The construction and arrangement ofl the parts of my device being thusmade known, the operation of the same will be readily understood. Whenthe wagon is on alevel road or an upgrade, the brake will not beapplied. Vhen the wagon is on a downgrade, the body will by its ownweight tend to move toward the front end of the running-gear, and, theplates J being free to slide on the plates M, said movement willbe'permitted, the supplemental reach being thus set in motion, and thelevers D consequently operated to apply the brake-shoes to the wheels,thereby retarding the motion of the vehicle. Vhen the wagon is on anupgrade, the body will tend to slide rearwardly, and this rearwardmotion will be prevented by the stops N on the plate M, so that the bodycannot slip from the running-gear.

My device is very simple and efficient and compactly arranged, and itsadvantages are thought to be obvious.

Having thus described my invention, what I claim, and desire to secureby Letters Patent, 1s#- l. The combination, with the running-gear andthe plates M, secured upon the ends of the bolsters, of the leverssupported by the running-gear and carrying the brake-shoes, thesupplemental reach connected to said levers, the secondary bolsterssecured to the supplemental reach, and the plates J, secured to saidsecondary bolsters and sliding on the plates IWI, as set forth.

2. In a wagon-brake of the character described, the combination of theplate M, having the dovetailed ribs on its side edges, the

plate'J, having ribs on its under side engagl ing said dovetailed ribs,andthe anti-friction rollers arranged between the said plates, as setforth.

3. In a wagon-brake of the character described, the combination of theplate M, having the ribs L and the stops N, the plate J, having ribs onits under side engaging the ribs L and stops N, and rollers 'arrangedbetween the said plates, as specified.

4. The combination, with the running-gear,
